Implement the algorithm in your favorite programming language. Choose P so that M will have more
than 10 million digits. The Electronic Frontier Foundation offers an award to the discoverer of
a ten million digit prime number.

(The catch is, state-of-the-art PCs will complete the test in
about five months for any given P. The chances of M being prime are about 1 in 250.000. Still beats
the lottery, though.)
